Dissimilarity between the Printer and the Plotter
1) Plotters print their output through moving a pen across the surface of paper's piece.
It implies that plotters are limited to line art quite than raster graphics as along with the other printers. They can draw complicated line art, consisting text, although do so very slowly due to the mechanical movement of the pen.
2) The other dissimilarity between the printer and the plotter is: the printer is intended primarily at printing text. Hence, the printer is sufficient to produce a page of output, but it is not the case along with the line art of the plotter.
